Matlab/Simulink Assignment: Work in Teams of at most 4 members

Group projects are meant for you to work together and learn from each other. It is expected that all members of the team will put reasonably equal amounts of effort, and most importantly, each member will learn as much as possible from the experience.

Consider the constant field, armature controlled DC motor model that includes the armature inductance from assignment A2.

1. Develop a Matlab script where one can enter the model parameters from a spec sheet. In this case use the Galil Motor spec sheet given in class. If a parameter is not given, make a reasonable engineering assumption.

2. Develop a Simulink diagram of the model 3. Set the armature voltage (input) to be a step input. Typically, armature voltages may be limited

to the range [-5, +5] volts. Obtain step responses for the motor angle (deg), speed (rpm) and armature current (A). As discussed in class, you may use the SCOPE feature in Simulink but also capture the data into the Matlab workspace and use the PLOT function to obtain the plots.

Your report should include the Matlab listing, the Simulink diagram, and any other analytical work.

Extra Points (5): solve the corresponding DFQs analytically and compare with the simulation plots.
